Thankyou for the info.I did try googling it but was unsucessfull. It goes to show what a fantastic pool of knowledge this forum is! As regards to heat I would think I have a friend who is a fabricator welder and I am sure we can make something up to fit over the tubes to create some form of heatexchanger.

If you need pictures of a 996TT turbo setup let me know. I have one of these cars up in the air right now sans rear bumper as I just installed the engine I rebuilt for it and haven't finished buttoning everything up yet.

Are you talking N/A or twin turbo headers?
The early 3.6L engine used the same bolt pattern as typical air cooled 911. Later air cooled engines had the flanges flipped. Water cooled engines are a completely different animal.
What are you trying to do?

hello Brian, yes my question was originally will 996 turbo headers fit a 964. It seems with mods to the flanges they will. (ihope so as i am picking a pair up on Saturday that I have agreed to buy) It appears that there is a shortage of 993 turbo headers on the used market. I am still fighting with the insurance company over the value of my burnt out 930,so I am looking at low cost options for turboing my 964.
